Using a router to create wood type only gets you near the finished product. There is one more step necessary after the router is used. By its very nature the router has a round bit and you can’t go any smaller or “sharper” that the diameter of the bit you are using. To create a sharp ‘inner’ angle, a graver or burin needs to be used to finish the job. The wood-type manufacturers employed skilled workmen to do this hand-finishing process in the manufacturing of wood type.
